Sweet Grass Hills
The Sweet Grass Hills (Blackfoot: ''kátoyissiksi'', Cheyenne: ''vé'ho'ôhtsévóse'', Salish: ''ččaɫalqn '', "three peaks" 〔Pete, Tachini. Seliš Nyoʻnuntn = Medicine for the Salish Language: English to Salish Translation Dictionary. 2nd ed. Pablo, MT : Lincoln, NE: Salish Kootenai College Press ; Distributed by University of Nebraska Press, 2010.〕) are a small group of low mountains rising more than 3,000 feet above the surrounding plains southwest of Whitlash, Montana in Liberty and Toole County, Montana.〔(【引用サイトリンク】title=Sweetgrass Hills )〕 The tallest point in the hills is West Butte at . Quite prominent in the local area, they are clearly visible from US Highway 2 to the south and can sometimes be seen as far north as the Crowsnest Highway (Highway 3) near Medicine Hat in Alberta. Other named peaks in the small group are Gold Butte (6,512 feet), East Butte (with two peaks, the taller of which at 6,958 ft), and Mount Lebanon (5807 ft).
The Sweet Grass Hills are an example of the island ranges that dot the central third portion of the state of Montana. These island ranges, completely surrounded by the 'sea' of plains and not geographically (or often geologically) part of the Rocky Mountains to the west, are "biological hotspots", containing more species than the prairie below.
==Formation and natural features==
The hills were formed in the early Paleogene period, and geologically are known as stocks - intrusive igneous rock forced up from below and solidified. Because of uplift and erosion, the overlying rock formations have disappeared. The upper slopes of the hills have not been glaciated and would have stood above the ice sheet that covered the area during the last ice age.〔 pp.84-85.〕 Since the Sweet Grass Hills are at a higher elevation than the surrounding prairie, temperatures are cooler and precipitation is higher. Forested areas, consisting mainly of Douglas fir, are therefore able to grow on the hills' slopes.〔
